Police were called about 2:15 p.m. to the lot adjacent to Starbucks when Marsteller reportedly overdosed in Porterfield’s vehicle.

Police learned Porterfield had gone to Pittsburgh, where she purchased the drug.

After Marsteller injected the heroin and overdosed, police said Porterfield disposed of the heroin and related paraphernalia inside the women’s restroom at Starbucks. The items were retrieved by police. Marsteller was treated at the scene by ambulance personnel.

Charges will be sent by summons from the office of District Judge Jay Weller.
